Analysis of impurities of cannabidiol from hemp. Isolation, characterization and synthesis of cannabidibutol, the novel cannabidiol butyl analog
Cannabidiol (CBD), one of the two major active principles present in Cannabis sativa, is gaining great interest among the scientific community for its pharmaceutical, nutraceutical and cosmetic applications. CBD can be prepared either by chemical synthesis or extraction from Cannabis sativa (hemp). The latter is more convenient from several points of view, including environmental and economic, but mainly for the absence of harmful organic solvents generally employed in the chemical synthesis.
